Abstract
A tubular stent formed from a plurality of cylindrical rings and connecting links where selected connecting links are of comparatively high mass in relation to the other links. The high-mass links have sufficient mass to be visible during a fluoroscopy procedure when formed from a moderately radiopaque material such as stainless steel. The high-mass links being arranged in a spiral pattern along the length of the stent to ensure that the stent is fluoroscopically visible regardless of the stents orientation during the implantation procedure.
